Hello!
Please help me, I spent all day googling for this issue but I could not find a solution!
What can I do to get rid off the error message "The specified network name is no longer available" when copying files from Windows 7 Professional to My Book World Edition White Light using smb protocol?
Thanks a lot for your help!

I guess the only way to regain access to your My Book is by pulling the power plug from the back of the unit, right?

What I've found in my particular case is that while copying multiple files to the Public folder, the My Book hangs as soon as a file larger than 2GB is copied over. Copying the larger than 2 GB files over one by one does work however, but isn't at all practical.

I get this error:"2010/01/04 00:13:49 read_data: read failure for 4 bytes to client 192.168.0.4. Error = Connection reset by peer"
in my logs all the time, even when it didn't seem to disconnect from windows and hangup! My log is completely filled up with this error message (and a few others).

I did not find the "getpeername failed. Error was Transport endpoint is not connected read_socket_with_timeout: client 0.0.0.0 read error = Transport endpoint is not connected" in my smb log though.

Hi!
Finally I solved the problem! The problem was my onboard Gigabit Lan chip from Realtek. I installed a PCI Gigabit Lan card with a VIA chip and now my file transfers work as expected! I also tested Gigabit LAN cards with Intel and Marvel chips and they all work fine.

That's interesting. It worked after you installed another LAN hardware. But in my case two computers have exactly the same problem with this NAS - and there was no problem with the previous Iomega HMND 1TB.

I have the same problem as you under Vista x64. And I have no idea how to solve it.

I am having a similar issue but its' not with large files. The problem I am having is I will loose connection to the NAS after a period of time. It would respond to pings but I can't http, ftp or anything into it.
